l 5 opening lo the blades may be turned le prevented from accidental toshoulder so ment by laised portion lo and provided 'with an elongatedslot23 ei;-

tending therethrough, and struck on the are 0l a circle. Vllhe base oroli'set 22 oli each blade is clamped down upon the cap proper by snindividual binding plete 2li, havingv sn to accommodate a screw 2S. Thescrew 26 clamps the binding plate 2d down on extension 22, end passesthrough opening` and slot 23 into the cap proper is inserted between thehead of this screw 2o and plate'24 a` spring Washer 27. Each oiiset 22hes upon its upper fece two raised portions 28 and .29, the function or"which will .herein later appear. Each plate 2e has on its lower face sdepression 30 and is ro- 25 `vided with tivo shoulders 31 and 32, the

functions otl which will also later more fully appear. rEhe raisedportion 30 performs no function. lt is merely s bulge in the metal dueto the indented portion 30. Plates 2l eo are also provided with openingsthrough `which pass binding screws 33 or securing the conducting wiresto the device.

Each binding plate 2d hss one its edges struck on the arc of a circle,so as to fit 35 against and contorni to the contour 0I" the oi chamber18, and each offset 22 has cte side its outer edge also struck on thearc circle for the same purpose.

llVith this arrangement, it will be seen that or adjusted vertically sothat theii` elongated sides may be brought i to various relations witheach other. When the blades are adjusted inthe parallel position shownin Fig. 2, they are displacement by 28 of eech blade engaging 30 of itsrespective binding the engagement raised portions with depression plate24, and also by of raised portion 29 oi" each blade with 32 ot itsrespective binding' plate 24. When the blades are turned Jfrom theposition shown in Fig. 2, so as to be in alii ement, as in Fig. 3, theyare held in this plisition against accidental displace- 29 engagingdepresl, end there y sion 30, .and also by raised portion 2dengaggingshoulder Si.

ln Fig. d, the blades are shown edjusted to a position Where theirextended sides are et right angles to each other. ln this cese, thelolsde 2l would be retained in position or locked, as described withreference to Fig. and the blade 20 would he retained or locked, asdescribed with reference to Fig. 3. The means provided iorloclringg orretaining the blades in the adjusted-'pol tion-is ot course auxiliary tothe clainpin, action ot plates 24, end l. do not wish vto be nn, stoodas limiting my invention to such ngssiliary retaining; means. n

The spring Washers 2 permit cil?" the adjustment of the ble( esWithoutnseesserily loosening screws 26., lt should lie under.V stood,however, that these Washers may be` dispensed with if desiree. lt shouldalso be understood that l do not liniit my invention to the particularadjustments ot the blades illustrated. i

lt will loe seen from the, foregoing description that a cap of this kindmay be used with any of the arrangements ot sockets illustrated in Figs.8 to ld, inclusive, or with receptacles having other errang-erneute ofsockets.

ln Fig, l, l have indicated my cap as applied to a common -torni olreceptacle 34.

"Without limiting my invention to the specific embodiment thereof hereinillustrated, what lclaim is l. A device ol' the class described,comprising; a cap, a Contact blade havinpg an offset or base provided`with an elongnted slotbe binding plate over seid offset, and :t screwpassing through said binding" plete and said offset into said cap. l

2. A device of the class described, comprising e csphaving a vrecessedend provided with e curved Wall, u contact blade having an offset orhase-.curved to conform to the curvature ot said Walhsaid offset havingan elongated slot therein, and having projections forming locking means,n bindingI plate over seid offset, and provided with shoulders to limitthe angular movement of said oli'set, a screw passing tlirougli saidbindingr plate und said offset into said cap, and a spring washerinserted between the head of said screw and said bindingplate.
